The complete chloroplast genome of the medicinal plant Angelica decursiva (Apiaceae) in Peucedani Radix.

ABSTRACT: Angelica decursiva (Miquel) Franchet & Savatier (Apiaceae) has been used as a significant medicinal plant in East Asia. We determined its complete chloroplast genome for the first time in this study. The complete chloroplast was circularized and had a typical quadripartite structure genome of 146?719?bp long including the large single copy region (LSC) of 93?256?bp, the small single copy region (SSC) of 17?497?bp and duplicated inverted regions (IRs) of 17?983?bp each. The total GC content was 37.56% and for the four structures it was 35.98% (LSC), 31.06% (SSC), and 44.83% (for each IR). There were a total of 113 genes, comprising four rRNAs, 29 tRNAs and 80 protein coding genes. In the phylogenetic analysis, A. decursiva was grouped with Seseli montanum. This study may contribute to authenticating the plant's correct use as medicine for health and provide an important genetic resource for phylogeny with related species.

Project description:Sophora tonkinensis belongs to genus Sophora of the Fabaceae family. It is mainly distributed in the ridge and peak regions of limestone areas in western China and has high medicinal value and important ecological functions. Wild populations of S. tonkinensis are in danger and need urgent conservation. Furthermore, wild S. tonkinensis resources are very limited relative to the needs of the market, and many adulterants are present on the market. Therefore, a method for authenticating S. tonkinensis and its adulterants at the molecular level is needed. Chloroplast genomes are valuable sources of genetic markers for phylogenetic analyses, genetic diversity evaluation, and plant molecular identification. In this study, we report the complete chloroplast genome of S. tonkinensis. The circular complete chloroplast genome was 154,644 bp in length, containing an 85,810 bp long single-copy (LSC) region, an 18,321 bp short single-copy (SSC) region and two inverted repeat (IR) regions of 50,513 bp. The S. tonkinensis chloroplast genome comprised 129 genes, including 83 protein-coding genes, 38 transfer RNA (tRNA) genes, and 8 ribosomal RNA (rRNA) genes. The structure, gene order and guanine and cytosine (GC) content of the S. tonkinensis chloroplast genome were similar to those of the Sophora alopecuroides and Sophora flavescens chloroplast genomes. A total of 1,760 simple sequence repeats (SSRs) were identified in the chloroplast genome of S. tonkinensis, and most of them (93.1%) were mononucleotides. Moreover, the identified SSRs were mainly distributed in the LSC region, accounting for 60% of the total number of SSRs, while 316 (18%) and 383 (22%) were located in the SSC and IR regions, respectively. Only one complete copy of the rpl2 gene was present at the LSC/IRB boundary, while another copy was absent from the IRA region because of the incomplete structure caused by IR region expansion and contraction. The phylogenetic analysis placed S. tonkinensis in Papilionoideae, sister to S. flavescens, and the genera Sophora and Ammopiptanthus were closely related. The complete genome sequencing and chloroplast genome comparative analysis of S. tonkinensis and its closely related species presented in this paper will help formulate effective conservation and management strategies as well as molecular identification approaches for this important medicinal plant.
